Two stationary particles of masses `M_(1)` and `M_(2)` are 'd' distance apart. A third particle lying on the line joining the particles, experiences no resultant gravitational force. What is the distance of this particle from `M_(1)` ?

Two bodies of masses 100kg and 10,000kg are at a distance of 1m apart. At what distance from 100kg on the line joining them will the resultant gravitational field intensity be zero?

Two masses 'M' and '4M' are at a distance 'r' apart on the line joining them. 'P' is point where the resultant gravitational force is zero (such a point is called as null point). The distance of 'P' from the mass '4M' is

Two particles of masses 'm' and '9m' are separated by a distance 'r'. At a point on the line joining them the gravitational field is zero. The gravitational potential at that point is (G = Universal constant of gravitation)

.Two particles of masses "m_(1)" and m_(2)(m_(1)>m_(2))" are separated by a distance ' "d" '.The shift in the centre of mass when the two particles are interchanged.

Two particle of masses m and 2m are at a distance 3r apart at the ends of a straight line AB . C is the centre of mass of the system. The magnitude of the gravitational force on a unit mass placed at C due to the masses is

Mass M is distributed uniformly along a line of length 2L . A particle of mass m is at a point that is at a distance a above the centre of the line on the its perpendicular bisector (Point P in figure). The gravitational force that the line exert on the particle is

In the figure given below, two particles of masses m and 2m are fixed in place on an axis. Where on the axis can a third particle of mass 3m be placed (other than at infinity) so that the gravitational force on it from the first two particles is zero?

Two particles of mass m_(1) and m_(2) , approach each other due to their mutual gravitational attraction only. Then

Two particles of masses 1kg and 2kg are placed at a distance of 50cm . Find the initial acceleration of the first particle due to gravitational force.
